Title: Understanding Fertilizer Dosage in Late Maturity Days for Paddy Crop
Introduction:
The late maturity stage of paddy crop, also known as the reproductive or grain-filling stage, is a crucial period when the plant’s energy is focused on grain production. Adequate nutrient supply during this phase is essential to achieve optimal crop yield and quality. In this article, we will discuss the importance of fertilizer dosage during the late maturity days of paddy crops and offer essential guidelines for ensuring healthy plant growth and maximum productivity.
The Nutrient Demands of Late Maturity Days:
During late maturity, paddy crops experience high nutrient demands, especially for nitrogen (N), phosphorus (P), and potassium (K). These macro-nutrients play vital roles in supporting overall crop growth, boosting photosynthesis, facilitating healthy root development, enhancing grain quality, and promoting adequate grain filling.
Fertilizer Dosage Recommendations:
1. Nitrogen (N):
N-demand during late maturity increases as the plant enters the grain-filling stage. Inadequate N-supply during this period can result in reduced grain weight and size. Typically, a paddy crop requires around 120-150 kg/ha of Nitrogen during the late maturity stage.
2. Phosphorus (P):
Phosphorus is necessary for energy transfer and root development. The recommended P dosage for late maturity paddy crops ranges from 60-80 kg/ha. Ensure well-distributed P application to promote uniform grain filling.
3. Potassium (K):
Potassium supports overall plant vigor, disease resistance, and water regulation. During late maturity days, paddy crops demand an estimated dose of 60-70 kg/ha of potassium. Adequate K supply helps improve grain quality, promote healthy panicle growth, and enhance drought resistance.
Other Essential Nutrients:
Apart from NPK, paddy crops also require trace elements or micronutrients for optimum growth. These include iron (Fe), zinc (Zn), copper (Cu), and manganese (Mn). Soil analysis can help determine if any deficiencies exist and a suitable dosage of these micronutrients.
Application Techniques:
To ensure efficient nutrient utilization and minimize wastage, consider the following application techniques during the late maturity stage:
1. Timing:
Apply nutrient doses at the beginning of the late maturity phase when the crop transitions from the vegetative to reproductive stage. This timing ensures nutrients are available right when the crop requires them the most.
2. Split Application:
Dividing the fertilizer dosage into multiple smaller doses, applied at regular intervals throughout the growth stage, allows for better nutrient absorption by the crop. Split applications minimize nutrient loss and improve fertilization efficiency.
3. Placement:
Ensure proper placement of fertilizer near the active root zone to facilitate easy access for the crop. Broadcasting or banding methods are commonly used for applying fertilizers in paddy fields.
Conclusion:
The late maturity days of paddy crops demand careful attention to ensure optimal nutrient supply. Following the recommended fertilizer dosage and application guidelines, particularly for NPK and micronutrients, can significantly enhance grain yield and quality. Additionally, farmers should consider soil testing and consult with agricultural experts for tailored fertilization strategies based on specific regional conditions. Proper fertilization practices during this critical phase will help farmers maximize their paddy crop’s potential and achieve sustainable agricultural productivity.
